Jessica and Ashlee Simpson’s parents Joe and Tina are divorcing after 35 years of marriage, according to a family rep.

“Tina and Joe Simpson have filed for divorce,” the statement reads (via Us Weekly). “It is an amicable split and there is no third party involved. Any other related allegations are completely false. The family appreciates your respect for their privacy at this time.”

A report from TMZ, however, suggests that the split wasn’t so amicable. According to court documents obtained by the gossip site, Jessica and Ashlee Simpson’s mom filed divorce papers in Texas last month, claiming that her marriage to Joe “has become insupportable because of discord or conflict of personalities.” Tina also claims she has “separate property” from Joe and wants to keep it.

Joe allegedly filed his own divorce petition days later, insisting Tina get nothing from the split, TMZ reports.

Joe and Tina Simpson rode on the coattails of their daughters’ fame, appearing on their MTV reality shows, Jessica’s “Newlyweds” and Ashlee’s “Ashlee Simpson Show.” Joe, a former pastor, acts as manager to both of his daughters.

Joe made headlines in early August when he was charged with two counts of DUI. He pled not guilty.
